Product details
Overview
SMB10J13AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 21.5 V clamping voltage (VC) at 46.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial power supply inputs.
For engineers reviewing the SMB10J13AHM3/H datasheet, SMB10J13AHM3/H pinout, SMB10J13AHM3/H application, or SMB10J13AHM3/H equivalent, key selection criteria include clamping performance under 1000 W surge, AEC-Q101 qualification for automotive use, unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to ESD and lightning-induced transients. Its low incremental surge resistance and stable clamping behavior ensure predictable protection during repetitive 8.3 ms half-sine surges up to 100 A (IFSM) and continuous operation from –55 °C to +150 °C junction temperature.
The SMB10J13AHM3/H is halogen-free and RoHS-compliant (HM3 suffix), qualified to AEC-Q101 for automotive applications, and rated MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal resistance (RθJA = 72 °C/W) reflects optimized PCB pad layout requirements for sustained power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC rail margin for 12 V systems. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA test current - guaranteed avalanche onset range ensures consistent turn-on across production lots. |
| VC @ IPPM | 21.5 V at 46.5 A - clamping voltage limits downstream IC stress during 10/1000 µs surge; critical for protecting 24 V tolerant receivers. |
| PPPM | 1000 W - peak pulse power handling with 10/1000 µs waveform; enables robust protection against ISO 7637-2 Pulse 1/2/5a in automotive ECUs. |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine); supports inrush current immunity in power input stages. |
| TJ max | +150 °C - maximum junction temperature; allows operation in under-hood automotive environments without derating. |
| Package | SMB (DO-214AA) - surface-mount outline with 2.20 mm height and 5.59 mm body length; compatible with standard SMT pick-and-place feeders. |

Applications
| Automotive Sensor Interface Protection | Industrial 24 V Power Input Stage |
|---|---|
|
Use Scenario: Protecting LIN/CAN transceiver I/O pins and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between signal line and ground, responding within <1 ns to limit voltage excursion below IC absolute maximum ratings. Use Value: Clamps to 21.5 V at 46.5 A, ensuring downstream 3.3 V/5 V interface ICs survive ISO 16750-2 pulses without latch-up or parametric shift. |
Use Scenario: Safeguarding 24 V DC input of PLC I/O modules and motor drive controllers against 1000 V/100 A surge events per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary front-end surge suppressor mounted directly at connector entry point, shunting energy before it reaches upstream DC/DC converters. Use Value: 1000 W PPPM rating and 100 A IFSM enable single-device compliance with Level 4 surge immunity without parallel staging or derating. |
| Consumer Appliance Motor Control Board | Telecom Power Supply EMI Filter Stage |
|
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers connected to microcontroller-based motor drivers. IC Role / Device Role / Timing Role: Unidirectional TVS placed across motor terminals or driver output pins to clamp flyback voltage during MOSFET turn-off. Use Value: 21.5 V clamping voltage prevents gate oxide damage to 25 V-rated logic-level MOSFETs while maintaining fast recovery for PWM frequencies up to 20 kHz. |
Use Scenario: Adding secondary surge suppression after common-mode chokes in AC/DC power supplies for base stations and optical network terminals. IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 13 V) used in differential mode across +24 V and return lines to absorb residual differential surges escaping primary MOV stage. Use Value: Low leakage (<1 µA) avoids loading filter capacitors; SMB footprint allows dense placement near EMI filter components without compromising creepage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J13AHE3/H | Same electrical specs (VWM = 13 V, VC = 21.5 V), but RoHS-compliant commercial grade (E3) without halogen-free certification. | Lacks AEC-Q101 qualification and JESD201 Class 2 whisker resistance - not approved for automotive under-hood use. | Select SMB10J13AHE3/H only for cost-sensitive consumer or industrial designs where halogen-free and automotive qualification are not mandated. |
| SMBJ13A-T | Identical VWM, VBR, and VC ratings; same SMB package; however, not AEC-Q101 qualified and uses legacy M3 suffix without HM3 halogen-free assurance. | No automotive qualification documentation; lower traceability for material compliance (e.g., IMDS reporting). | Choose SMBJ13A-T only for prototyping or non-automotive production where Vishay HM3-specific environmental compliance is unnecessary. |
Compared with SMB10J13AHE3/H and SMBJ13A-T, the SMB10J13AHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and full traceability for automotive Tier 1 BOMs - making it the sole option when both regulatory compliance and under-hood reliability are mandatory.

FAQ
What is the clamping voltage of SMB10J13AHM3/H and how is it measured?
The SMB10J13AHM3/H has a maximum clamping voltage (VC) of 21.5 V, measured at a peak pulse current (IPPM) of 46.5 A using the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and reflects the actual voltage seen by downstream circuitry during transient events - critical for ensuring protected ICs remain within their absolute maximum ratings.
Is SMB10J13AHM3/H qualified for automotive applications?
Yes, SMB10J13AHM3/H is fully AEC-Q101 qualified, with test evidence covering HTGB, HTRB, temperature cycling, and ESD per JESD22-A114. The HM3 suffix confirms halogen-free, RoHS-compliant construction and JESD201 Class 2 whisker resistance - all documented in Vishay's official AEC-Q101 certificate for this part number.
What does the "HM3" suffix indicate in SMB10J13AHM3/H?
The "HM3" suffix in SMB10J13AHM3/H denotes halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance requirements, along with MSL Level 1 rating for lead-free reflow. It distinguishes this variant from E3 (RoHS only) and HE3 (AEC-Q101 + RoHS) versions - confirming full automotive environmental compliance for SMB10J13AHM3/H.
Can SMB10J13AHM3/H be used in bidirectional configurations?
No, SMB10J13AHM3/H is strictly unidirectional, as confirmed by its part number structure (no "C" suffix) and datasheet designation. Bidirectional variants carry "CA" suffixes (e.g., SMB8J13CA). Using SMB10J13AHM3/H in bidirectional circuits would result in forward conduction during negative transients, potentially damaging the device or failing to protect.
What PCB pad layout is required for optimal thermal performance of SMB10J13AHM3/H?
SMB10J13AHM3/H requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88422 fig. 2. This layout achieves the stated RθJA of 72 °C/W; reducing pad area increases thermal resistance and risks exceeding TJ max = +150 °C during repeated 1000 W surges - especially in enclosed automotive enclosures.
